Re: Need help with a service program

John,

It looks to me that one or more parameter definitions changed.
Check a compile listing of the old version and compare it to a compile
listing of the new version.
The signature violation between a program and a service program is similar
to how a program gets a level check with a file that has changed.

No parm changes, just internal code changes.

Here is the error from the joblog,

John,

Did you change the number of parameters or the size of any of the
parameters?
What error messages you are getting when you execute the service program?

I'm not sure I understand your question. I modified code inside of
function SCGETNVP. I did not add a new function. Does that answer
your question?

Buck has the right suggestions. Question: Why is your export *CURRENT
and *PRV the same?

I've done something wrong and have no clue what. We have a

and stuff is blowing up all over with Signature Violations.

In the BND source, we have the following:

What piece did I miss?

If you could post the CRTSRVPGM command you used, we'd be able to
pinpoint it. Best guesses:

1) EXPORT(*ALL) instead of *SRCFILE
2) EXPORT(*SRCFILE) with the wrong SRCFILE() specified. Like test
vs production.

Further diagnostics:
Do a DSPSRVPGM to see what the current signature is.
Do a DSPPGM to see what signatures the calling programs expect.
